Answer: 2.5 minutes
Explanation: Divide the time by the amount of pages to find the amount of time spent of each page. (30/12=2.5)
Answer:
= 9
Step-by-step explanation:
The given parameters are;
The point of intersection of the perpendicular bisectors of the sides
,
, and
intersect (meet) at point G
Let D represent the point of intersection of the perpendicular bisector from G to
, we have for ΔBGD and ΔCGD;
≅
by reflexive property
∠GDB = ∠GDC = 90° given that
is the perpendicular bisector of 
Similarly,
≅
, also given that
is the perpendicular bisector of 
Therefore;
ΔBGD ≅ ΔCGD by Side-Angle-Side (SAS) rule of congruency
≅
by Congruent Parts of Congruent Triangles are Congruent, (CPCTC)
=
= 9 by definition of congruency
∴
= 9.

=============================================================
Explanation:
BC = 78 is parallel to the midsegment DE.
This parallel midsegment is half as long as BC, so DE = BC/2 = 78/2 = 39
-------
DF = 34 doubles to AB = 2*DF = 2*34 = 68, since the midsegment is half as the parallel side, so we just think in reverse of that process.
-------
BE = 34 for two reasons
- Quadrilateral EBFD is a parallelogram with opposite sides BE and DF that are congruent.
- E is the midpoint of AB, so BE is half as long as AB
--------
We don't use the info that AC = 48.
7 2/5 is a mixed number for 37/5.
